We were experiencing the same issue" Error 5,2,0 " and some users just had "Error 0"
I was able to resolve the issue by making Edge open in compatibility mode for Windows 7. However we found that the compatibility mode only stuck for the initial launch of the application. Any time the user closed the application and reopened the compatibility mode settings were reverted.
We ultimately had to add a registry entry to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers
to always have Edge open in compatibility mode for Windows 7.
New String Value
Value Name: C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe
